It happens to me Ernie
Excaliper Ernie at idle with a 70 amp alt putout about 45 amps the load was this 3 coolant fans 22 amps
msd system 9 amps
ecu for fi 6 amps
fuel pumps (2) 14amps
lights ipc and gauges 5amps.
under drive pulleys cut 10% of out put at idle
the battery is not being charged because amps needed is more than ALT output. 56 amps drain, 45 amps charging at idle. This doesn't include the 5-10% fudge factor of the charging system. Max power of my 70 amp alt was 61-65 amps when hot. I have had to recharge the battery more than once. That was a 600cca battery I now run an 875 one and have less problems. New alt fixed all problems now. No theory here Ernie. Have also redone the alt cable #4awg and added a mega fuse to protect the wiring harness and replaced the amp meter with a voltage meter. Is not period correct but safer IMO. Rick L. Ps Ernie you have to remember that the orginals didn't need half of the power we need today.
